Summary

Effluent: Farmed cockles are not provided nutrient fertilization. Effluent may be released from the hatchery or nursery phases, but this is not considered to have any negative effects on the environment, and filter-feeding of cockles during grow-out is often cited as improving water quality and/or nutrient cycling in the vicinity near farms. In isolated cases, anti-predator netting or other plastics may be unintentionally released from the farm, but this is not typical, particularly in regions that dominate cockle production globally.

Habitat: Farmed cockle grow-out operations are primarily located in intertidal or shallow subtidal environments of estuaries, coastal lagoons and bays, all of which are generally considered high- value environments. However, the impact of farmed cockle operations on habitat is considered to be minimal, with the main concerns stemming from bio-deposition and harvest.

Feed: Cockle farming does not require external feed. Cockles obtain nutrients by filtering water, which also serves to improve water quality and/or nutrient cycling in the vicinity near farms.

Disease: Diseases in farmed cockles can occur at every stage of production, from the hatchery to grow- out. Farmed cockle grow-out systems are open to the natural environment and there is the possibility of disease exchange between wild and farmed animals. However, biosecurity measures have been put in place from the individual farm level to the intergovernmental and international levels, which reduce the risk of parasite and pathogen infection.
